Preface

Congratulations on your purchase from the Dimension series of Ethernet switches.

This preface introduces you to the ES-3124PWR and discusses the conventions of this User’s Guide. It also
provides information on other related documentation.

About the ES-3124PWR

The ES-3124PWR Ethernet switch is a managed switch with features ideally suited in any environment with
unshielded twisted pair (UTP) wiring. It can deliver broadband IP services to:

¾ Multi-tenant unit (MTU) buildings (hotels, motels, resorts, residential multi-dwelling units, office

buildings, educational establishments, etc.)

¾ Public facilities (convention centers, airports, plazas, train stations, etc.)

¾ Enterprises.

It can also be deployed as a mini-POP (point-of-presence) in a building basement delivering 10/100Mbps data
service over Category 5 wiring to each customer.

General Syntax Conventions

¾ This guide shows you how to configure the switch using the web configurator and CLI commands. See the

online HTML help for information on individual web configurator screens.

¾ Mouse action sequences are denoted using a comma. For example, click Start, Settings, Control Panel,

Network means first you click Start, click or move the mouse pointer over Settings, then click or move
the mouse pointer over Control Panel and finally click (or double-click) Network.

¾ “Enter” means for you to type one or more characters. “Select” or “Choose” means for you to use one of

the predefined choices.

¾ Predefined choices are in Bold Arial font.

¾ Button and field labels, links and screen names in are in Bold Times New Roman font.

¾ “e.g.” is a shorthand for “for instance”, and “i.e,” means “that is” or “in other words”.

Dimension ES-3124PWR Ethernet Switch

Chapter 1

Getting to Know the ES-3124PWR

This chapter describes the key features, benefits and applications of the ES-3124PWR.

The ES-3124PWR is a stand-alone layer 2 Ethernet switch with 24 10/100Mbps ports, two RJ-45 Gigabit (1Gbps or
1000Mbps)/mini-GBIC (Gigabit Interface Converter) combo ports for uplink, two RJ-45 Gigabit ports for stacking
and a console port and a management port for local management. A combo port contains one Gigabit port and one
slot for mini-GBIC transceiver (SPF module).

With its built-in web configurator, managing and configuring the switch is easy. From cabinet management to port­level control and monitoring, you can visually configure and manage your network via the web browser. Just click
your mouse instead of typing cryptic command strings. In addition, the switch can also be managed via Telnet, the
console port, or third-party SNMP management.

1.1 Features

The next two sections describe the hardware and firmware features of the ES-3124PWR.

1.1.1 Hardware Features

Power

The ES-3124PWR requires 100~240VAC/10A power.

PoE (Power over Ethernet)

The switch can provide power to a device (that supports PoE) such as an access point or a switch through a
10/100Mbps Ethernet port.

24 10/100 Mbps Fast Ethernet Ports

Connect up to 24 computers or switches to the 10/100Mbps auto-negotiating, automatic cable sensing (auto-MDIX)
Ethernet RJ-45 ports. All Ethernet ports support:

¾ IEEE 802.3/3u/3z/3ab standards

¾ Back pressure flow control in half duplex mode

¾ IEEE 802.3x flow control in full duplex mode

Two Gigabit Ethernet Ports for Uplink Modules

The gigabit ports allow the ES-3124PWR to connect to another WAN switch or daisy-chain to other switches.

Two Slots for Mini-GBIC Modules

The mini-GBIC (Gigabit Interface Converter) module transceivers allow flexibility in connection options. You can
use mini-GBIC transceivers for fiber connections to backbone Ethernet switches.

Security

¾ System management password protection ¾ Port-based VLAN

¾ IEEE 802.1Q VLAN ¾ 802.1x Authentication

¾ Limit dynamic port MAC address learning ¾ Static MAC address filtering

Port Link Aggregation

The ES-3124PWR adheres to the 802.3ad standard for static and dynamic port link aggregation.

Bandwidth Control

¾ The ES-3124PWR supports rate limiting in 1Mbps increments allowing you to create different service

plans.

¾ The ES-3124PWR supports IGMP snooping enabling group multicast traffic to be only forwarded to ports

that are members of that group; thus allowing you to significantly reduce multicast traffic passing through
your switch.

¾ Broadcast storm control

Quality of Service

¾ Eight queues so you can ensure mission-critical data gets delivered on time.

¾ Follows the IEEE 802.1p priority setting standard based on source/destination MAC addresses.

STP (Spanning Tree Protocol) / RSTP (Rapid STP)

(R)STP detects and breaks network loops and provides backup links between switches, bridges or routers. It allows
a switch to interact with other (R)STP-compliant switches in your network to ensure that only one path exists
between any two stations on the network.

Cluster Management

Cluster Management allows you to manage switches through one switch, called the cluster manager. The switches
must be directly connected and be in the same VLAN group so as to be able to communicate with one another using
same cluster management implementation.

1.2 Applications

This section shows a few examples of using the ES-3124PWR in various network environments.

1.2.1 Backbone Application

In this application, the switch is an ideal solution for small networks where rapid growth can be expected in the
near future.

The switch can be used standalone for a group of heavy traffic users. You can connect computers directly to the
switch’s port or connect other switches to the ES-3124PWR.

In this example, all computers connected directly or indirectly to the ES-3124PWR can share super high-speed
applications on the Gigabit server.

To expand the network, simply add more networking devices such as switches, routers, firewalls, print servers etc.

Figure 1-1 Backbone Application

1.2.2 Bridging Example

In this example application the switch is the ideal solution for different company departments to connect to the
corporate backbone. It can alleviate bandwidth contention and eliminate server and network bottlenecks. All users
that need high bandwidth can connect to high-speed department servers via the switch. You can provide a super­fast uplink connection by using an uplink port on the ES-3124PWR.

Moreover, the switch eases supervision and maintenance by allowing network managers to centralize multiple
servers at a single location.

Figure 1-2 Bridging Application

Full-duplex mode operation only applies to point-to-point access (for example, when attaching

the switch to a workstation, server, or another switch). When connecting to hubs, use a standard

cascaded connection set at half-duplex operation.

1.2.3 High Performance Switched Workgroup Example

The switch is ideal for connecting two power workgroups that need high bandwidth. In the following example, use
trunking to connect these two power workgroups.

Switching to higher-speed LANs such as FDDI or ATM is not feasible for most people due to the expense of
replacing all existing Ethernet cables and adapter cards, restructuring your network and complex maintenance.

The ES-3124PWR can provide the same bandwidth as FDDI and ATM at much lower cost while still being able to
use existing adapters and switches. Moreover, the current LAN structure can be retained as all ports can freely
communicate with each other.

Figure 1-3 High Performance Switched Workgroup Application

1.2.4 IEEE 802.1Q VLAN Application Examples

This section shows a workgroup and a shared server example using 802.1Q tagged VLANs. For more information
on VLANs, see the Switch Setup and VLAN Setup chapters in this User’s Guide. A VLAN (Virtual Local Area
Network) allows a physical network to be partitioned into multiple logical networks. Stations on a logical network
belong to one group. A station can belong to more than one group. With VLAN, a station cannot directly talk to or
hear from stations that are not in the same group(s) unless such traffic first goes through a router.

Tag-based VLAN Workgroup Example

Ports in the same VLAN group share the same broadcast domain thus increase network performance through
reduced broadcast traffic. VLAN groups can be modified at any time by adding, moving or changing ports without
any re-cabling.

VLAN Shared Server Example

Shared resources such as a server can be used by all ports in the same VLAN as the server, as shown in the
following example. In this example, only ports that need access to the server need belong to VLAN 3 while they
can belong to other VLAN groups too.
